LOCALIZATION VERSUS BAND CROSSING TRANSITIONS IN A MULTIBAND MODEL OF SPATIALLY DISORDERED MATERIALS
A theory is developed to describe the electronic densities of states and localization characteristics of a multiband tight-binding model for a system characterized by quenched liquid-like disorder. For the case of an sp 3 system, and with parameters appropriate to fluid mercury at an independent ele...

| description | A theory is developed to describe the electronic densities of states and localization characteristics of a multiband tight-binding model for a system characterized by quenched liquid-like disorder. For the case of an sp 3 system, and with parameters appropriate to fluid mercury at an independent electron level of description, the role of localization is found to be important: localized Fermi-level states persist up to densities considerably higher than that at which the s-p band gap closes. © 1990 American Institute of Physics. |
